YETI Rambler 18 Oz Bottle Chug

With a shatter-resistant Chug Cap built for controlled gulps, the YETI Rambler 18oz Bottle in Stag Red is designed for drinking on the move rather than sipping through a straw or a narrow spout. It holds 532ml in kitchen-grade stainless steel, with double-wall vacuum insulation and a No Sweat exterior that stays dry in your hand even with a cold drink inside. At 0.6kg empty it has some genuine heft, reflecting the amount of steel used in the build.

Key Features

• 532ml capacity: A solid, everyday amount for a workout, a walk or a few hours out of the house.
• Kitchen-grade stainless steel: Puncture and rust resistant, BPA-free.
• Chug Cap: A shatter-resistant, dishwasher-safe spout built for quick, controlled gulps.
• Double-wall vacuum insulation: Keeps drinks cold for hours with a No Sweat exterior.
• 100% leakproof: Sealed fully when closed, so it can go in a bag without worry.
• Interchangeable caps: Swap the Chug Cap for a Straw Cap or other Rambler cap options.
• Dishwasher safe: Lid on the top rack, gasket in the utensil basket.

At Urban Industry We Recommend These For

• Gym sessions and training, where the Chug Cap allows quick gulps between sets.
• Commuting and daily carry, where 532ml covers most of a working day.
• Sports and outdoor activity, where drinking quickly matters more than sipping slowly.
• Anyone who finds a straw cap too slow and prefers a more direct drinking action.
• Keeping cold water on hand through a warm day without needing to refill constantly.

Fit & Sizing Recommendations

• Based on our experience with this brand's sizing: 532ml sits below the 26oz bottle, better suited to a few hours out than a full day away from a tap.
• At 7.6cm wide, it fits most bag pockets and larger cupholders, though it's worth checking against a smaller cupholder first.
• The Chug Cap is fixed to this bottle rather than swapped for a straw as standard, though YETI's caps are interchangeable if you want to change it.
• The No Sweat exterior means it's comfortable to hold even filled with ice water, without a damp bag or desk.

Washing & Care Instructions

• Wash the lid on the top rack of the dishwasher, keeping the gasket in the utensil basket.
• Hand wash the body in warm soapy water if you'd rather not run a full cycle.
• Avoid carbonated drinks and contents above 85°C, both of which YETI advises against.
• Rinse it out daily to stop residue building up, especially with flavoured drinks.
• Dry the cap fully before closing it again to prevent trapped moisture.
